This request passwd to login to nodes, but 2 massages in the line, I can only success with one node, the 2sd. refussed.So, how I can do as you advise, to login to each node without being prompted for a password. ?
What I need to do. Help me.I run openmpi 1.2.9 supporting SGE (when I buil with --with-sge). I had tested to buil with 1.3. or 1.4. with this option I saw the error no recognize --with-sge. Why ? bug or ? While docs README shows that this is supported. I need this because I run SUN gridengine on may cluster. You have some ideals ?
Thank you very much.Sincerely.HTCuoc

Now for more processes:[guser1@ioitg2 examples]$ /opt/openmpi/bin/mpirun -np 6 --hostfile myhosts hello_cxxguser1@node1.ioit-grid.ac.vn's password:
